Sreeja updated HDDS-15456:
--------------------------
Description:
Implement a read-only SCM metadata scanner that opens the provided {{scm.db}}
and performs container lookups in the {{containers}} column family. For each
unique container ID discovered during the DataNode container scan HDDS-15455,
determine whether the container exists in SCM metadata and retrieve its
lifecycle state.
Build a lookup result containing:
* *{{NOT_IN_SCM}}* for container IDs that do not exist in SCM metadata.
* *{{DELETED}}* for container IDs whose SCM lifecycle state is {{{}DELETED{}}}.
Containers present in SCM with any other lifecycle state do not need to be
included in the result.
The resulting lookup information will be used by subsequent analysis steps to
identify orphan containers (wrt SCM) and deleted-but-present containers.
